SWITCH.

Application led May 5, 1911.

ticularly yto that class most generally known under the title of combination automatic and hand operated switches.

An object of this invention is theprovision of a switch of this character, which comprises suitable mechanism for the purpose of operating the same by means carried upon an approaching train, and also for the purpose of locking the switchin an open position.

Another object of this invention is the provision of arailway switch which may be manually operated for the purpose of opening and closing the same independently of the automatic train-operated means. A

A further object of this invention is the provision of a switch of this character, which is adapted to be operated by an appreaching train, the said switch being so constructed that in the event of the engagef ment of any undesired object between the rail points which will serve to prevent the same from closing it will be returned to its original position, at which point it will be locked against displacement.

A still further object of this invention is -toimprove and simplify devices of this character, rendering them comparatively simple and inexpensive to manufacture, reliable and eficient in use, and readily operated.

With the above and other objects in view, this invention resides in the novel features of construction, formations, combinations and arrangements of parts to be hereinafter more fully described, claimed and illustrated inthe accompanyingdrawings, in which- I Figure 1 is a plan view of a portion of a railway track having my invention applied thereto; Fig. 2 isa vertical, longitudinal sectional view through the switch stand;y

' Referring to the drawings by characters of reference, the numeral 1 designates gen-V erally a railroad track of the usual construction, which consists of a main linev 2 and a siding 3. The rails 4' in the main line and the siding are mounted upon the customary ties 5, and connected through the medium of switch points 6.o'f any customary type. These switch points 6 are connected at their free ends by a rod 7, which is connected at one end to a link 8 extending from the switch stand 9, supported upon the extended ends 10 of the ties 5.

The ends of several of the ties are extended a distance from the switch stand, as indicated by the numeral 11, to provide a support for the trip mechanism 12.- This trip mechanism 12 is carried by a longitudinally extending horizontally disposed plate 13, secured to the ties by bolts 14, or any other suitable fastening means, the said plate having secured to its upper` face angle bars 15, the horizontal flanges 16 of which are riveted, or otherwise secured, as at 17, to the said plate 13, while the upward or vertically extending flanges 18 of which have pivoted to their rear ends, as indicated by the numeral 19, an upwardly slanting operating member 20. This operating member 20 has hinged to its free end, as indicated by the numeral 21, a downwardly slanting member 22, which is provided at its lower extremity with a pair of oppositely extending trunnions 23, which project through slots 24 formed in the forward ends of the Hanges 18. An apertured ear 25 is formed upon the downward terminal of Patented Dec. 8, 1914.

the operating memberv 22, and is connected,`

by means of a bolt to an operating rod 26. A collar 27 is held adjustable upon the klink 8 by any desired means, and engagesI one face of a pair ofv springs 28, the outer face of one of which is bolted, or otherwise rigidly secured, a-s indicated by the .numeral 29, to a transversely extending upwardly projecting plate 30 formed upon the inner ends of a. horizontally disposed plate 31, which is'bolted, or. otherwise secured, as indicated by the numeral 32, to the intermei L,dia-teportion ofthe forward end of the plate 13. Aleaf spring 33 is secured to the rear end of the plate 13 in any desired man- K ner, and engages the under face of the operating member 20, for the purpose of yield! i its frontl truck a downwardly extending arm 35, provided with an `enlarged head 36, which is adapted to engage the operating member 20, for the purpose of forcing the rod 26 longitudinally with respect to the track .and operating the mechanism contained within the stand. i

The switch stand 9 comprises a base plate 37, which is bolted, riveted, or otherwise secured to the-extensionslO of the ties, preventing any undesired displacement there from upon the operation ofthe mechanism contained therein. A rectangular housing 38 extends upward froml the base plate 37, and is provided at its upper edges with a horizontal flange 39,` from Iwhich projects a cylindrical casing 40, provided at its upper end with an annular flange 41, and being partially closed by a horizontally disposed plate 42, which is provided with a conceiitric opening 43, through which extends a vertically disposed operating shaft 44. The shaft 44 has keyed thereto, adjacent the upper end of the casing 40, a locking plate which consists of a cylindrical body portion 46,?from which project'extensions 47, adapted to be seated within the oppositely offset' sides 48 of a circular seat 49 formed inthe upper face of a revolving plate 50 mounted upon the shaft 44 and restingv upon the flange 42, being held thereon against displacement by integral fingers 51, which pro jectvradially from the said plate 50v and extend under theannular flange 41.

vIOne side of the plate 50'has formed thereon a pair of cars 52, between which are piv-` oted, as indicated by the numeral 53, a hand operating lever 54. This lever 54 is provided at a point intermediate its ends with a socket 55, adapted to receive one of'a pair of lugs 56 projecting outwardly from the Vcasing 40, to which the lever may be secured to hold the same against displacement by means of a padlock, yor other suitable fastening device', not shown in the drawings. The lower extremity of the shaft 44 is provided with a 'crank arm 57, to the lower end of which is secured, by means of a cotter pin 58 or the like, the apertured end 59 of the link8. Obviously when the lever 54 has been released from the lugs 56, the same may be swung upward and the plate 45 revolved, rotating the shaft 44 through the medium of the beforementioned means, for the purpose .of'throwing the switch points into and outV of engagement with the rails. In order to permit the lever 54 to be' moved downward into'engagement with the lugs 56, the

Aflange 41I is notched, as at 60,l which, other "than permitting thev lever v54 to be moved downward to a vertical position, also serves to. lock the plate 45 against rotation.

A suitable signaling device 6l is secured to the upper end of the shaft 44, and consists of a series of radially extending blades V 62, of the usual design, above which isv mounted a lantern- 63, which `serves to give the desired signalfafter dark. An operating slide; 64 is longitudinally movable through the slots 65 formed in either end of the rectangular` housing 38. This slide 64 is substantially L-'shaped in cross section, beingconnected at one end by means of a triangular plate 66, from the center of which extends a lug 69, to which is connected the bifurcated end of the operating'rod 26.' The vertical flange of the slide 64 is'slotted, as indicated by the numeral 71, to permit the passage therethrough of an armv 72, which extends outwardly from the sleeve 7 3 secured to the shaft 44, being held thereon against any undesired vertical displacement by a collar 74, upon which the sleeve 73 rests. The side of the collar opposite the one from which the arm 72 exi tends is offset, as indicated by the numeral 75, and provided with an arm 76, in the end of which is formed al slot 77, through which extends a bolt 78 secured to the said arm 76. An arm 79, which extends at an angle to the arm 72 from the sleeve 79, is keyed, as indicated by the numeral 80, to the shaft 44. A spring 81 is'secured, by means of the bolt 78, in engagement with the arm 7 6, which serves to yieldingly hold the arms 72 and 79 at an obtuse angle with respect to each other through the tension spring 81, which may be adjusted by means of a locking nut 82, which is threaded upon the free endof the bolt 7 8; j

The shaft 44 is vertically movable through the switch stand, and is provided adjacent l,

and extends through a slot 87@ formed in the horizontal plate of the slide 64 to provide a means whereby when the said-slide is moved longitudinally, the shaft 44 will be raised, which disengages the locking member 45 from the recess 49 and permits the said shaft to rotate. This shaft 44 is normally forced downward through the medium `of a spring 88, which restsagainst the lower face of the plate 42 and the upper edge of a collar 89, adjustably secured to the shaft 44 by means of a set screw 90.v Obviously the longitudinal movement of the slide 64 throws the switch points into engagement with the rails, and in order to lockl these switch points in their. proper position, a

i catch 91 which is in the form of a plate 92 is hinged, as indicated by' the numeral 93, to the laterally extending end 94 of a vertical plate 95, which is bolted, riveted, or otherwise secured, to one end of the rectangular extension 38. The forward terminal of the plate 92 is provided with a dependingtapered rib 96, which is adapted to engage the rear face of a tapered locking boss 97 formed upon the before-mentioned slide 64.

In order to insure the downward movement of the catch 91, a leaf spring 98 is secured to the plate 95, and curved downwardly to engage the upper face of the plate 92, serving to force the same into a horizontal position.

A link 99 is pivoted to an upwardly extending lug 100 formed upon the upper face of the plate 92, adjacent the free end thereof, andk is pivotally secured to a downwardly slanting. arm 101 formed upon a rod 108 of the lever 54, as clearly illustrated inv Fig. 3 of the drawing. Obviously, when the lever 106 is moved uponits pivotal point to a position which raises the arm 105, the latch 91 will be raised, which releases the rib 96 from the tapered boss 97, and permits the slide 64 to bereturned to its initial position.

A vertically extending rod 109 is journaled at its reduced opposite ends in the plate 37 and flange 39 respectively, and has formed thereon an arm 110, which is adapted to lie in the path of the arm 79 and limit the rotation of the shaft 44 in case a foreign object engages the switch points. This armv 110 is yieldinglv held in the path of the arm 79 by meansr of a leaf spring 111, which is the numeral 112, vto one face of the arm` 110,

and lying in engagement with the inner face I of one wall of the rectangular extension 38.

A laterally extending arm 113 projects from the lower extremity of the rod 109, and is pivotally connected to a link 114, which link inturn is connected at its opposite end to a swinging bar 115 carried by a vertical rod 116, mounted at its opposite reduced ends, as indicated by the numeral 117, t0 the forwardlyl extending arms 118 formed upon a vertical plate 119, bolted, or otherwise rigidly'secured, to one wall of'thehousing 38. The opposite end of the swingingv bar 115 is extended, as indicated by the/numeral 120, above the upwardly extending flange of the slide 64, for engagement with a-projection 121 formed thereon. The extremity 120 of the swinging bar 115 is arranged to engage the downwardly slanting arm 87 for operating and raising shaft 44. A depending extension 122 projects downwardlyand rearwardly from the rod 102, and engages the upper forked end 123 of a vertical arm 124 formed upon the arm 113 adjacent its pivotal connection with the link 114.

The operation of the device is as follows: lVhen it is desired to operate the switch by hand, the arm 54 is released from the lug 56 and the plate 50 rotated thereby until the said lever engages 'the opposite lug 56,to

which it may `be secured in retaining the switch in its locked position. The rotation of this plate 50 obviously rotates the shaft 44, which causes the switch pointsV to be thrown through the medium of the rod 7 and link 8 connectedfto the crank previously described.

The-device is automatically operated as follows: As the train advances toward the switch, the enlarged end 36 of the arm 35 obviously engages the operating member 20 lying in the path thereof, forcing the same, together with the member 22 downward against the tension of the springs 33 and 28, causing the rod 26to be moved forwardly, operating the slide 64. As the slide 64 starts in its longitudinal movement through the switch stand, the rear edge of' slot 71 coming in contact with the arm 72 causes the shaft 44-to be operated after being raised through the medium of the arms 85 and 87 and supporting rod 86, as will be clearly apparent from Fig. 2 of the drawings. As shown in Figs. 3 and 4, the arm 113 integral with is in the position'it assumes prior to the engagement of the arm 72 by the end of the slot 71, the relative position of which is shown in-Fig. 2.` The arm" 79 is shown in Fig. 4 as about to engage arm 110 to dispose this arm to the position shown in Fig. 5, b

which movement the arm 114 displaces the end 120 of the swinging bar 115 from the p0- arin 57, as

shaft109 and lying belowvthe plane of112 A 96, all of which is accomplished in the early part of the movement of slide 64 before the end of slot 71has passed the rib 96. When the slide 64 has been fully thrown by the mechanism operated by the shoe on the `enginev and the arm 8 encounters an opposition caused by a foreign object lying between the switchpoints, the shaft 44; is prevented from revolving in its normal manner by the pressure of the foreign object. .The arm 7 9 isthusprevented from engaging arm 110 for thereason that although it has risen to the plane Aof 110 by the action of arm 87, shaftl has not been permitted to complete its revolution because of the obstacle between the switch points and instead of passing this arm asvnormally provided, arm 110 remains4 in contact with it which supports the4 rib 96 holding it out of engagement with the locking boss 97 at the endof the move- Then it is desired to release the switch by ject engage the switch points which would prevent their opening to the full extent, the` slide 64 will be operated to its full extent, but as the armr 79jengages the arm 110, which obviously forces the same outward, causing the latch tobe raised and retained in lits raised position by the action of theV vertical arm ltand forked end 123 formed thereon, the switch points will be immediately returned to their closed position,

when the arm 36 carriedby theengineis moved from engagement with the operating members 20 and 22 of the trip mechanism,

From the foregoing disclosures, taken in' connection with the accompanying draw-` ings, it will be manifest that a switch of the nature describedv 1 is provided which will fulilall of the necessary requirements of.

such a device. Y. n
